TDA Datasheet. You can also watch this video for an overview of the design process. At the end of the video I wire up the amp and play some music so you can hear what it sounds like:. The goal is to find a transformer that can output a maximum supply voltage close to the maximum supply voltage needed by your amplifier.
A 15 V transformer will give me So anything over a VA transformer will supply my amplifier with enough power. The TDA needs to be attached to a heat sink or it will quickly overheat and get damaged.
But before we can do that, we need to know the values of the three thermal resistances in the path of heat flow away from the TDA The thermal resistance of thermal paste is usually around 0. Heat sinks with a lower thermal resistance will dissipate more heat.
It depends on your input voltage, speaker impedance, and desired output power according to this formula:. If your minimum gain value allows for it, a good gain to use for home listening is around 27 to 30 db. A tolerance of 0. If the resistance values between the two channels are off by a few Ohms, the gains will be different and one side will be louder than the other. These resistances will set my gain to:. This difference in current needs to be minimized since it will create a DC voltage at the inputs that will be amplified as noise.
The cutoff frequency of this filter should be set 3 to 5 times lower than the cutoff frequency of the input high pass filter. Now lets check to see if 1. This filter has two functions. The cutoff frequency of this filter should be greater than the 20 kHz upper limit of human hearing. I decided on a cutoff frequency of kHz, which is well below kHz and well above the 20 kHz upper limit of human hearing.
A Zobel network helps to prevent oscillation that can occur from the parasitic induction of speaker wires. There is one set of decoupling capacitors for each voltage supply pin. Grounding is one of the most important aspects of amplifier design.If Subwoofer in your music system is not producing enough bass then you can use this simple DIY circuit to enhance the Bass.

It has the ability to deliver the output of 18 W. We have connected a 2. So that it allows only the high frequency audio signal. There is a resistor R4 between pin 2 and 4 we called that resistor as Feedback Resistor.
This feedback resistor is used to obtain the gain. If the feedback resistor is improper then the subwoofer amplifier will not work properly. In the circuit diagram, resistor R1 and a capacitor C2 are connected in series, with pin 2 of the TDA to suppress the noises in the audio signal.
Pin 3 is grounded, means connected to negative terminal of power supply. The output of the TDA is connected with the series capacitor of the value uf to allow amplified signal to the speaker. The pin 5 is having a resistor of k which functioned as the voltage divider biasing.
This sub-woofer circuit has the capacity to deliver 12 W output. We can we can use speaker of 4 to 6 ohm speaker. It will be better if we use a heat sink to remove the high temperature in the TDA If necessary you can also add a cooling fan for the better working. For the volume adjustment we are using 22 kilo ohm variable resistor. Connect the audio signal wire to the any one end of the variable resistor and connect the center pin to the input signal C1 of the capacitor.
And connect the ground to the other end of the variable resistor. By changing the variable resistor we can change the volume of the subwoofer of td IN diode is used to avoid interchange of polarity of IC to avoid from burning and two capacitors C7 and C6 are used to eliminate the noises present in the power supply.
The resistor R6 and C5 are also helps to avoid the unwanted the noises in the speaker Blur sounds. I used 12v smps as power supply to power the entire circuit. For Connecting the 3. In below picture blue wire is ground and yellow wire is audio signal. Then connect the audio jack to mobile or laptop to enjoy music.
So this is how, we can easily build the Subwoofer amplifier circuit using TDATDA is an audio amplifier which provides an output power of 14 Watts. It has internal protection system against short-circuits and overloads which limits the dissipated power.
It is basically designed for use in applications requiring a class AB amplifier of a low frequency. TDA audio amplifier amplifies the audible signals from any audio device for example microphone by enhancing its volume when that sound is played on a speaker.
Due to its small size, minimum cost and the feature of providing output power from 10 to watts, this IC would be best for designing audio amplifier circuits. In addition to that, it can perform a stable operation and has good input sensitivity. If you are designing a high-volume system, bridge amplifier or a booster amplifier with the above-mentioned features, then using TDA will be a good choice as it is easy to use.
The operation of this IC is similar to other general operational amplifiers. The only difference is that it amplifies audio signals. A simple application circuit of this IC is given below. It is responsible for obtaining the gain of an amplifier.
The capacitor is connected at pin 2 which allows only high-frequency components of signals to pass through it while blocking lower frequency components.
A resistor of 4. This capacitor is used to allow the amplified output signal to the speaker which in turn will produce the high volume sound. It is used to change the volume of the speaker. BY supplying the circuit with power supply, an amplified signal is obtained at the output whose volume can be adjusted through a potentiometer. You can connect an audio jack at Vi.
Connect this jack with a mobile phone or any other audio device and you can enjoy your music. It is available in the TO package consisting of 5 pins. The 2D model of this IC along with dimensions is given below:. Notify me of follow-up comments by email. Notify me of new posts by email.

C11 and C12 provide power filtering. RP1 is the volume contrl. IC1 and IC2 provide the amplification. C1 and C6 are input coupling capacitances. C4 and C9 are the output coupling capacitances. R6, C5 and R12, C10 aid high frequency stability on the output. The order of soldering is not particularly important. But here's a suggested order. Position one of the heatsinks in its holes behind the IC and make sure the IC and the heatsink holes line up.
Solder one of the IC pins and one of the heatsink pins so they are still adjustable. Ensure the hole alignment is good and screw the IC to the heatsink tightly without overforcing. Click to edit.

So pls post here how this circuit works. Thank you so much for sharing this datasheet to us, and I also find all kinds of pdf on the electronic components online shopI hope it will help you. Post a Comment. November 01, One of these few is SGS's used in the present amplifier.
The design of the amplifier is straightforward: a power op-amp followed by two output transistors. The supply current to the IC varies in accordance with the input signal. Consequently, there will be a similarly varying voltage drop across resistors R6, R7, R8, and R9 since these are in the supply lines to the op-amp.
As long as the current is lower than about 1A, the voltage drop across the resistors will be insufficient to switch on transistors T1 and T2. This means that outputs up to 2 W into 4 ohm are provided entirely by the op-amp.
Once the output current exceeds a level of 1A, the transistors are on and contribute to the power output. When the Input signal is small, there no quiescent current through the transistor, but there is through the op-amp. Crossover problems are thus obviated.
How to Design and Build an Amplifier With the TDA2050
Since the IC also provides thermal compensation, stability of the operating point is ensured. The supply voltage may lie between 12 V and an absolute maximum of 44 V. Construction of the amplifier on the printed-circuit board should be straightforward. The transistors as well as the IC must be fitted insulated on to a heat sink of about 2 k W.
Use plenty of heat conducting paste. The supply line should be protected by a 3. TDA Technical Data:. TDA Circuit diagram:. R1-R4 - KOhm R5 - 8.
